Estimation of Volumetric Mass Transfer Coefficient in Bioreactor
...Show More Authors

 

This study is concentrated to investigate the effects of aeration and stirring speed on the volumetric mass transfer coefficient (KLa). A dynamic technique was used in estimating KLa values in order to achieve the aim of this study.

This study was done in 10L bioreactor by using two medias:-

  1. Dionized water
  2. Xanthan solution (1 g /L)

Moreover, the research covered a comparison between the obtained values of KLa.

The Xanthan solution was used because of its higher viscosity in comparison with water. It behaves similarly to the cultivation medium when organisms are cultivated in a bioreactor. Growth of organisms in the reactor leads to a change in the viscosity of the medium which affects the mass transfer.

Two variables, the effect of air flow rate (3-20 L/min) and the effect of stirring speed (250-700rpm) on KLa value were studied. Other parameters such as temperature, liquid volume, and stirrer shape and stirrer position were held constant; the results demonstrated an increase in KLa – value and mass transfer with increasing stirrer speed. Thus at higher speed, better dispersion of the bubbles was obtained. Therefore, that increased the surface / volume ratio which increased the mass transfer area i.e. KLa value.

Normalizing Society in George Lamming’s In the Castle of My Skin
...Show More Authors

This study examines the effect of colonialism on Caribbean society during the colonial period. Through normalization, the British colonial power diminished Caribbean identity and planted a new hybrid identity. Discipline institutions and surveillance techniques had a vital role in normalizing Caribbean society. Caribbean authors have adopted this notion of normalization to represent the reality of colonialism and its consequences. George Lamming, one of the Caribbean political activist and influential novelist in his novel In the Castle of My Skin (1953), reflects normalization as theorized by Michael Foucault. Lamming depicts the story of villagers and their life under colonial domination. Through discipline institution, like school, colo
